IMPROVED mom son rtmrtnmc SKIRT-WIRE.

TO ALL WHOM .IT MAY CONCERN:

Be it known that I, JOHN H. MONK, of BrooklymE. D., in the county ofKings, and State of New York, have invented,'madc,. and applied to use acertain new and useful improvement in Means for Tempering Skirt- Wire,tire. and I do herebydeclare the following to be a full, clear, andexact description of the said invention, reference being had to'theannexed drawing, making part of this specification, wherein- Figure 1 isa section longitudinallyof the tempering-trough, and

lijigure 2 is a transverse section of the same.

Similar marks of reference denote the same parts. I l

In tempering skirt-wire, it is usual to employ a bath of melted lead,across which two metal bars are placed, and the wire led beneath thesebars. The constant rubbing of the wire as it is drawn along wearsnotches speedily in these bars, and when a join or inequality in thewire'comes to such'notch itis very liable to catch and be broken.Besides this, where a. wider wire is'drawn along in a place where anotch has been worn bya narrower wire, oize. edge enters such notch and.the other does not, and a twist is given to'the skirt-wirein temperingwhich renders a separate straightening operation indispensable. It alsois important thatthc means for keeping the wire down into the-meltedmetal be adjustable, in order that any variation in the depth of meltedmetal may be accommodated, and that the warping or twisting of the potunderttheheat'may be easily compensated,- in order that the wire, inbeing drawn along, may be exposed to exactly the heat required.

The nature of my said invention consists in a pair of adjustable groovedrollers applied in such a manner to the bath of melted metal as toovercome all the difiiculties aforesaid, and insure the perfecttempering of the skirt or other wire, as hereafter specified, the saidrollers revolving by the contact of-the wire.

In the drawing, a is the pot forming the tempering-bath, the same beingproperly set, andhca'ted so as to fuse the tempering-metal. b and c aregrooved rollers, each of which is set in bearings 01 d, that are withinstationary slides e e, and are adjustable by screws ff. Each groove inthe rollers band 0 is widerthan the p ,widest skirt-wire that is to betempered on the machine, and the rollers are placed near'the ends of thebath,

their lower sides being below the surface of the melted metal. Theskirt-wire is drawn. through the melted metal to temper the same, andthe rollers 25 and a keep it down below the surface of the metal, andin-a straight position between one roller and the other.' The ends oftherollers being set in adjustable bearings, allow of their being raisedor lowered, so as to immerse the wire to be tempered more or less belowthe surface, according to the amount of heating required in thetempering, and one end of the rollers may be immersed more than theothers where two sizes or qualities of wire are being run through at thesome time, the journals fitting loosely in the hearings to allow of thisslight diagonal position of the rollers, so that they will revolvefreely by the contact of the wire being tempered.

Several wires can be run through at thesame time, and there is noliability for the wire to become caught or broken, and there is nostationary surface for the wire to run over, which would be worn intonotches or grooves.

In order to keep the rollers free from dirt or any accumulation ofdress, I make use of scrapers g, hung on the cross-shafts 7t, and byhaving a separate scraper to each groove-they act much better inremoving any obstructions, and if the obstruction is not removed bycoming into contact with the scraper the'iirst time, that scraper willrise and not lift the other scrapers.

What I claim, and-desire to=seeure by Letters Patent, is-' A pair ofgrooved rollers, adjusted substantially as specified, in combinationwith the pot or bath for-melted metal for tempering wire for skirts,860., in the manner set forth.

' In witness whereof I have hereunto set my signature this twentieth dayof July, 1866.
